HIGHLIGHTS
- who: Brando Bellazzini and colleagues from the Institut, Gif-sur-Yvette, France have published the research work: Beyond Positivity Bounds and the Fate of Massive Gravity, in the Journal: (JOURNAL) of 17/04/2018
- what: In this Letter, the authors show that qualitatively new bounds, stronger than standard positivity constraints, can be derived by taking into account the irreducible IR cross sections under the dispersive integral, which are calculable within the EFT.
SUMMARY
